Edit: We have released a patch Minion 3.0.6 that updates Minion to include an about page (See the ( i ) icon in the upper right hand corner of Minion) that lists all current software we use with links to the projects. We also package all the license text inside the Minion jar file and we will be working in our next release to have those licenses even more accessible by including them in the users ~/.minion folder too.
